Cy3-PEG-SH (MW 5000)

Cy3-PEG-SH (MW 5000) is a fluorescent labeling reagent that combines Cy3 fluorescent dye, polyethylene glycol (PEG) and sulfhydryl (SH) derivatives, and is suitable for molecular coupling. SH is highly reactive and can react with a variety of functional groups (such as maleimide) to form stable thioether bonds[1].
